HEADLIGHT.

lights, of which the following is a specifica-- tion. 1

.This invention relates to headlamps ofv ,the character generally used on motor operated vehicles, and it is the purpose of they invention to improve the construction of said lamps, so that theduty of replacing new bulbs or repairing the electrical connections with the bulbs are materially facilitated.'

In carrying out the invention. it is my pnrposelto providea headlamp wherein the rear wall of the lamp casing includes a detachable portion which supports the electric light and socket, and the connection between 'the' detachable portion and the lamp' casing is such that said portion can be qucklyf-and easily detached from the casing, so that the bulbcan be readily replaced, .or an inspection and repair made of the electrical connect-ion with the bulb should the occasion require.

The nature and advantages of the invention will be better understood when the following'det-aileddescription is read in clonnection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts las claimed. -V

In the dra-wings forming part of this application, like numerals of reference indicate similarpartsin the several views, and wherein: p l a Figure 1 is a lvertical sectional view through a headlamp constructed in accordance with one embodiment of the invention showing the association of the parts.

Figure 2 is a viewv similar to Figure 1 showing the removable portion of the lamp casing separated from Ithe latter, and-the bulb partly retracted from the lamp casing.

I-igure 3 is a sectional view taken on the line 3-3 of Figure 1. l

Figure 4 is a plan view of the retaining ldisk or plate'for the removable portion of the lamp casing.,

" Figure 5 is a view in elevation of the re movable portion of the lamp casing. Figure 6 is a view similar to Figure 1 of a modified construction.

Figure 7 is a view similar to lFigure 2 of said modified construction.

Figure 8 is a view in elevation ofthe removable portion of the lamp casing.

Referring to thel drawings in detail, and particularly' to Figures 1 to 5 inclusive, I

vhave shown a headlamp of the drum type now usually employed on' motor operatedvehicle's. The lamp'casing is indicated at 10 and includes a rear wall, `the. front of said casing being closed by means of the usual lens 11. The reiiector is indicatedat 12, the' electric light bulb at 13, and the usual 'socket for said bulb'is indicated at 14. All of these features are of the same general construction as those now in use, eX- cept that the rear wall of the lamp casing includes a removable portion which constitute-s the center of this wall, and is of cap like formation as clearly shown in `F1gures- 1 and 5. The removable cap like portion 15 is adapted to fill the enlarged central opening formed in the rear wall 16 of the casing'when the parts are associated, while the cap 15 itself is provided with a central opening surrounded by a liange 17 to accommodate the electric .light socket 14. The cap like portion 15 is formed with an annular bead 18 which bears against the outwar'dly dared on curved portion 19 of the rear wall when the partsare assembled as shown in Figure 1. 'The annular portion 20 of this cap is formed on its inner edge with substantially hook like elements 21 which are designed to engage the edge 22 of the enlarged-opening formed in a retaining plate or disk 23 which is'secured to the inner side of the rear wall 16 of the lamp in any .suitable manner and isv formed with an enlarged central opening to receive the lamp socket 14, to cooperate. with the removable cap 15 to hold the latter operatively associated with the lampr casing proper.

There are preferablyY threeJ of these hook like elements 21 carried by the cap, a'nd for each element 21, the edge 22 of the opening of said plate 23 is formed with a notch`24,

so that the elements 21 can be initially pol sitioned in said notches incident to the association of ysaid parts, and the cap 15 subsequently turned 1n either direction to cause the elements 21 to embrace the edge 22 of .the plate as shown.' The tension of these elements 21 holds thecap 15 in place.

By reason of the construction shown and thus far described, it is obvious that the cap can be quickly and conveniently i separated from the rear wall 16 of the lamp l these facts, the necessity of removingy the casing, and separated from said casing in the manner shown 1n Figure 2, so that access may be readily had to the electric light bulb to replace the latter, or to repair any of the electrical connections as the occasion may require. Again, by reasony of hook like elements 21 into the notch 24 of the retaining plate 23 in order to remove the cap from the rear Wall of the lamp casing, and inasmuch as the electric light socket 14 is connected with this cap, it is of course simultaneously removed fro/m the casing therewith. i

In Figures 6 to 8 inclusive, I have shown the invention employing a lamp of a different configuration, and wherein the lamp casing is substantially dome shaped and indicated at 28. This casing is provided with an enlarged opening at the rear thereof, and the edge of this opening is offset'in- Wardly as at'29 thereby providing a shoulder 30 which surrounds the opening referred to. Carried by the casing 28 are headed studs 31 there being preferably three of these studs equidistantly spaced about the said opening and in close proximity to the shoulder v32. The opening at the rear of the lamp casing is in this'instance closed by means of a removable vplate which may be properly termed a cap indicated at 32, and which cap is provided with a central opening surrounded by a flange 33 which receives and embraces 'the electric light bulb socket 34. The electricV bulb is of course indicated at 35 and is associated with the socket in the usual well known manner. The cap 32 is ldesigned to conform to the curvature of the casing 28, and when associated with-the latter, the edge 36 of said cap bears against the annular shoulder 30 of said casin and' is supported by the inwardly offset ange 29 above referred to.

Projecting from the edge 36 of this cap at equi-distantly spaced points are hook like elements 38 which are also slightly olfset as shown to lie upon the outer surface of the lamp casing 28 and to extend beyond the shoulder 30, these hook like elements 38 are adapt-ed to receive the headed studs 31 carried by the lamp casing to hold the cap associated with the latter. It is only necessary to arrange the hook like elements in position to receive the `headed studs 31 incident to the -positioning of the cover or cap 32 on the flange 29, and subsequently turn the cap a slight distance toward the right in order to position the hook like elements over the studs 31.

In this form of the invention the bulbV can be just as easily retracted from the lamp casing as in the form hereinabove described, in that it is only necessary to give the cap 32 a slight turn. to the left to disengage the hook like elements 38 from the headed studs 31 whereupon the cap 32 together with the electric light socket l34 and bulb 35 can be removed or separated from the lamp casing for the purpose mentioned,

lWhile it is believed that from the foregoing description, the nature and advan-j tages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

Having thus described the invention, I claim: i

The combination with an automobile lamp having an openingin its rear end,

ture.
